4 hr 15 East, 1 hr 20 at DUB, 5 hr 5 West with reporting an hour before, that's a 10 hour 25 day on an aeroplane with two loads of passengers and meals. Not sure I'd be bidding for that gig!
Compared to a 10h flight to Izmir with Aer Lingus with an extra 76 passengers. Meal services is probably hard however once its done, its an easy flight compared to similar hops in Europe. Given the choice I think most might pick T/A flight.
